Should this upper work on my Oly K30R ?

Postby JCS » Thu Apr 28, 2016 5:44 am

Hi - I'd like to pick up a 9mm upper for my Oly AR - K30R - should this one, below, work?

http://palmettostatearmory.com/psa-9mm-16-mid-1-10-upper-with-hybrid-bcg-and-ch.html

I'm wondering about the part where the description refers to "To use with PSA lowers that use either Colt® or Glock®-style Magazines." - I'm also wondering where I'd get 9mm magazines for this one.

Thanks!

I am guessing "no" probably not. But honestly I am not sure about that at all. There are dedicated 9mm lowers out there and if the PSA is made to fit a dedicated lower (That's how it seems to read), then that's probably that.

Oly makes a nice 9mm upper, and there are others out there that do fit standard lowers.

Still looking for an Oly 9mm upper - I've located a used Oly K9 - would the upper that comes on the Oly K9 fit on my Oly K30R?

Thanks - I will likely go with the Oly magazines to avoid having to use the mag block - what'd be required for me to have an Oly lower, an Oly 9mm upper, that'd use Glock mags?

that's a good plan ...

a 'complete' Olympic Arms® K9-GL carbine model unit ...


these are your Olympic Arms® 9mm pistol caliber magazine configuration choices ... these newly released pistol caliber polymer magazines

or one of the older style modified STEN mags with it’s welded on mag-block adapter.

or one of the even older style magazine blocks; but none of these will work with a Glock® magazine ... only the K9-GL

This upper WILL NOT work on the Oly K30R lower. The page specifically says that it is only compatible with PSA lowers.

Additionally, if your desire is to use Oly magazines, you have to have an Oly Arms 9mm upper.

Skip the PSA unit and buy an Oly upper direct from the factory. Better product, proven design The ORIGINAL 9mm conversion mind you...), lifetime warranty - and requires no modification to your lower whatsoever.

"Skip the PSA unit and buy an Oly upper" - that's the direction I'm heading in . . .

I ended up buying a complete K9 9mm Oly AR - and several Oly 9mm magazines - AND the loader - the gun runs like a champ. FWIW, my Chiappa 22LR upper also runs great on my Oly 7.62x39 AR-15.

Now, I'm looking for a 5.56 \ .223 upper that'll run on my Oly lowers - I'll need .223 magazines - and obviously a .223 upper - I'll look for an Oly upper, but a buddy is offering me a great deal on a .223 \ 5.56 AR upper - can I use pretty much any standard AR-15 magazines and pretty much any .223 \ 5.56 upper? THANKS!

Good for you, I am sure you will be happy with your purchase prize! Yes, and you can use any upper made to work with a standard lower.
